Summer brings heat, sunshine… and a silent invasion: bugs that sneak through windows, cracks and even sliding guides. They’re annoying, unhealthy, and difficult to combat without resorting to chemical-laden sprays that can harm your health, your pets, or the environment.

But there is a 100% natural, economical and effective alternative to keep your home free of insects: a homemade spray that is applied to the window guides and works as an instant repellent.

Why do insects appear in window slides?

The guides are ideal places for dirt, humidity and organic debris to accumulate that insects use as a refuge. In addition, as they are enclosed spaces and difficult to access, they often go unnoticed in daily cleaning.

Therefore, applying a natural barrier directly there helps prevent its entry into the home and break its reproduction cycle.

What ingredients do you need?

All easy to get and economical:

• 1 cup distilled or previously boiled water
• 2 tablespoons ground coffee (can be reused)
• 1 tablespoon ground cinnamon
• 3 tablespoons ethyl alcohol
• (Optional) a few drops of citronella or eucalyptus essential oil

Step by step: how to prepare the natural repellent spray

1. In a bowl, mix the coffee with the cinnamon.
2. Add the alcohol and water, and stir well until everything is integrated.
3. If you have it, add 5 or 6 drops of the chosen essential oil.
4. Filter the mixture with a fine sieve to prevent the spray from clogging.
5. I poured the liquid into a spray bottle.

Always shake before use.

How is it applied?

Spray the liquid directly on:

• Sliding window guides
• Door frames facing the outside
• Dark or damp corners where bugs often appear
• Areas such as grates, baseboards or under furniture

Apply every 3 days or after a deep cleansing to maintain the effect.

What bugs does this mixture repel?

• Common and fruit flies
• Ants
• Bed bugs
• Small cockroaches
• Moths
• Little spiders

The combination of intense odors and components such as alcohol and cinnamon acts as a multisensory repellent: it disorients, discomforts and repels insects without the need to kill them or use poisons.

Advantages of natural spray

• Non-toxic: Safe for households with infants, allergy sufferers, and pets
• Does not harm the environment: does not release volatile compounds such as chemical aerosols
• It’s inexpensive: all ingredients are for everyday use
• Easy to prepare and apply

Extra tips to keep the house free of insects

• Clean window guides at least once a week with a fine brush or vacuum cleaner.

• Ventilate the rooms and avoid leaving stagnant sources of humidity.
• Place aromatic plants such as mint, basil, or lavender in pots near windows and doors.
• Use cloth bags with cloves and dried laurel in closets and drawers.

Warnings

• Always test the spray on a small area before using it on painted or varnished surfaces.
• Store the jar in a cool place and out of reach of children.
• If you have an allergy to cinnamon or alcohol, wear gloves or avoid direct contact.
